Experimental investigation of silicone impression materials

Abstract

Silicone impression materials are widely used in orthodontic practice for dental impressions, but they can be used in different applications. One potential application is the use of protective obturators during anaesthesia prior to cleft palate surgery. These silicone materials come from various brands with different material properties, which can influence the final product. Thus, these different mechanical properties were examined experimentally. Tensile tests were performed on specimens prepared with the use of 3D printed moulds and their structure was investigated by micro-CT.
